Cholera bacteria stab and poison enemies at predictable rates

The enemies were thrown together, so the killing began. Brandishing harpoon-like appendages covered in poison, two armies of cholera bacteria stabbed each other, rupturing victims like water balloons. Scientists at the Georgia ...

Looking for entangled atoms in a Bose-Einstein condensate

Using a Bose-Einstein condensate composed of millions of sodium atoms, researchers at the Georgia Institute of Technology have observed a sharp magnetically-induced quantum phase transition where they expect to find entangled ...

Reversible saliva allows frogs to hang on to next meal

A frog uses its whip-like tongue to snag its prey faster than a human can blink, hitting it with a force five times greater than gravity. How does it hang onto its meal as the food rockets back into its mouth?

Millions of tweets analyzed to measure perceived trustworthiness

By scanning 66 million tweets linked to nearly 1,400 real-world events, Georgia Institute of Technology researchers have built a language model that identifies words and phrases that lead to strong or weak perceived levels ...

Advanced materials power next-generation molecular separations

Chemical separation processes account for as much as 15 percent of the world's total energy consumption. Development of next-generation molecularly-selective synthetic membranes will be among the drivers for more efficient, ...

New low-cost technique converts bulk alloys to oxide nanowires

A simple technique for producing oxide nanowires directly from bulk materials could dramatically lower the cost of producing the one-dimensional (1D) nanostructures. That could open the door for a broad range of uses in lightweight ...

How a moon slows the decay of Pluto's atmosphere

Pluto's relationship with its moon Charon is one of the more unusual interactions in the solar system due to Charon's size and proximity. It's more than half of Pluto's diameter and orbits only 12,000 or so miles away. To ...
